General Safety Instructions
The econoVap steam humidifier has been designed and constructed in accordance with the latest technology and
the accepted safety regulations. The user is obliged to pay attention to these safety instructions as well as the
specific regulations for installation and the safety and accident prevention regulations in the country of operation.
The operating instructions should always be readily available at the place of operation of the humidifier.
All installation and service work must be done only by persons qualified to perform such work.
Proper use
The steam humidifier econoVap is intended solely for indirect or direct air humidification according to this manual.
Used in any other way beyond this description is contrary to its intended usage.
The manufacturer/supplier cannot be held responsible for any damage resulting there from.
Alterations to the humidifier
Without NORDMANN’s written approval, no alterations must be made to the humidifier.
Only original spare parts and options are allowed to be used.
Safety signs
Attention, Warning, Danger:
This sign warns of a possible dangerous situation. Disregarding this warning can lead to an injury of the operator or
to a damage to the instrument.
Attention, Voltage:
This sign warns of dangerous electrical voltage. Disregarding this warning can lead to danger or injury of the user.
NORDMANN humidifiers use ordinary tap water to produce steam. The water is converted directly into steam in a steam
cylinder by electrode heating using electrical energy. In so doing, the water acts as the electrical resistance. Vaporisation
occurs at atmospheric pressure (non-pressurised).
The electronic control system, with its microcontroller, regulates the
vaporisation process in accordance with the reliable principle developed
by NORDMANN, which allows rapid output changes. The humidifier
adapts itself automatically to the quality of the water used. Due to this
ability to set the optimum water concentration in the steam cylinder,
changes in the steam output are effected by minimal adjustments of the
water level, allowing the unit to react quickly and accurately to any set
point change. The use of fuzzy logic technology improves controllability. The adaptive control technique regulates the conductivity/mineral
concentration in the steam cylinder achieving ideal operating conditions
while maximising operational reliability.
The output fluctuations, which occur during normal operation, are kept
to a minimum by the automatic water-intake and drainage functions.

3.2 Steam Nozzle
For smaller outputs of up to 4 kg/h steam, we offer a nozzle which can be either fitted in
air ducts, for instance, or used for direct room humidification. The rules for vaporisation
lines (lines needed to mix the steam adequately with air) must be observed here too.
When the steam nozzle is used, the length of the steam hose should not
exceed 1.5 meters.
